Chapter 1: GENERAL INFORMATION

Introduction

The B&B Electronics 3PCIOSD1x single port isolated serial interface card is designed for IBM compatibles with a PCI Bus. The PCI design is Plug and Play compatible which allows the driver and Operating System to select the IRQ and addresses used by the card.

The 3PCIOSD1x cards offer exceptional setup flexibility with a mix of selectable operating modes. If you are writing your own applications, be sure the communications routine used supports Windows communication drivers and a wide range of COM ports.

Description

The isolated single port can be configured for RS-232, RS-422, or RS-485 data protocols. The RS-485 mode automatic Send Data Control feature transparently handles the enable and disable functions of the RS-485 transceiver. Buffered, high speed UARTs (16550A or 16850) make it ideal for high speed (modem) and multitasking applications.

Features

•IBM compatible, PCI Version 2.1 bus

•Supports baud rates to 460.8K baud with 4X clock option enabled

•Provides 2000 VDC minimum isolation on all lines from the DB- 25 male connector to the host computer

•High speed 16 byte FIFO 16550A UARTs (Model 3PCIOSD1A), 128 byte FIFO 16850 UARTs (Model 3PCIOSD1B)

•RS-485 Automatic Send Data Control or RTS control

•2-wire or 4-wire RS-485 operation (half or full duplex)

•120Ω Termination Select Jumper for RS-422/RS-485 Networks

•RS-232 Mode Signal lines: TD, RD, RTS, CTS, DTR, DSR, & DCD, and Signal Ground.

•2 Channel RS-422 Signal Lines: TD(A), TD(B), RD(A), RD(B) and Signal Ground.
